Application filed June 23, 1915. Serial No. 35,816.

To all whom it may concern:

Be it known that we, LOUIS -M. BROWN and ALBERT A. MAoLEoD, citizens ofthe United States, residing at Beverly and Swampscott, respectively, inthe county of Essex and Stateof Massachusetts, have invented certainImprovements in Work-Supports for Shoe-Machines, of which the followingdescription, in connection with the accompanying drawings, is aspecification, like reference characters on the drawings indicating likeparts in the several figures.

This invention relates primarilyto Work supports for shoe machines andis herein shown as embodied in Work positioning means particularlyadapted for use in machines which operate to trim the edge of an insoleafter the insole is attached to a last. In the manufacture of some typesof shoes, such as welt shoes, it is the usual practice, after the insoleis attached to the bottom of the last, to trim the heel portion of thein sole to the edge contour 'ofthe heel seat of the last. A machine forthis purpose forms the subject-matter of United States Patent No.1,076,431, granted October 21, 1913 on the application of E. L. Keyes.The insole is attached to the last usually'by means of a pluralityoftacks driven along the middle of the forepart and shank and by a singletack at the heel seat driven into the last through an opening in themetal anvil plate with which the heel end of a last is usually provided.The tacks along the forepart and shank may be driven at random, but theheel seat tack must enter the comparatively small opening in the anvilplate; Asa result the material of the last Where the heel seat tack isdriven is worn away with comparative rapidity so that finally a tackdriven at this point fails to hold the heel portion of the insolesecurely. There are in use, moreover, in the manufacture of some classesof shoes, lasts in Whichno opening is provided in the metal anyil platefor the reception of a tack and in which it is not desirable to providesuch an openinglest the strength of the plate be weakened unduly.

The machine shown in the patent above reierred to ineiades a yieldingpressesmam her for engaging the bottom face of the insole close to thepoint of operation of the cutter toprevent the insole from beingdeflected by the cutter in such a manner as to be trimmed unevenly.While this arrangement has proved to be satisfactory in operation underthe usual working conditions, it is not always sufliciently efi'ectivewhere the insole is insecurely tacked at the heel seat or where there isno heel seat tack. This arises largely from the fact that during thetrimming operation there is rubbing engage- 'ment between the pressermember and the insole which tends to neutralize to some extent theclamping efi'ect of the presser member.

An important object of this invention accordingly is to provide for usein a machine for trimming an insole attached to a last improved meansfor positioningthe insole in relation to the last. To this end a featureof the invention consists in a novel construction and arrangement ofwork positioning means including a clamp member arranged to engage thebottom faceof the insole and to turn with the last during the trimmingoperation, this member, in the illustrated construction, being movablerelatively to the last in engaging or releasing the insole. As a furtherfeature also the invention provides means convenient for manipulation bythe operator to enable him to efiect and main tain'engagement of theclamp member with the insole, Without interfering with such movements ofthe work support and the last as are necessary in order to presentdifierent portions of the edge of the insole in position to be trimmed.The construction shown includes a hand lever .for controlling theclamping or unclamping of the insole, this lever being mounted upon themovablework support convenient to that hand of the op-- upon the bottomof the last arranged to be moved to operative position through saidmaintaining it when idle in a position convenient for the reception of alast.

Still another feature consists in a last support having novel means forengaging the sides of the last to position it upon the support. Theconstruction shown includes members movable to engageopposite sides ofthe neck of a last combined with means for applying pressure upon thebottom of the last arranged to cause said members to be moved inwardlytoward the last upon the application of pressure to the last bottom.

The invention also includes, as a further feature, a swinging worksupport, and novel means tending to counterbalance the sup.- port so asto facilitate manipulation of the work. The invention also includes anovel construction for supporting the edge of the insole adjacent to thepoint of operation of the cutter, and a novel combination of operatingand supporting instrumentalities comprising a clamp member for firmlypositioning an insole on a last.

The above and other features of the invention, including certain detailsof con struction and combinations of parts, will now be described withreference to the accompanying drawings, .which illustrate a preferredembodiment of the invention, and will be pointed out in the claims.

Although the invention is illustrated herein in its application to amachine for trimming an insole attached to a last, it will be understoodthat in its broader aspects the invention is not thus limited but isapplicable in many of its features to use with different classes of shoemachines for performing various operations in shoe manufacture.

Fig. 7 is a front elevation of the lower portion of the work supportingmeans.

The machine illustrated in Figs. 1 and 3 comprises a frame 2 havingbearings for a rotary shaft 1 which carries a toothed cutter 6 and theusual shield 8.

Positioned at the end of the cutter is a guide member 10 constructed forengage ment with the lateral surface of a last, as a, adjacent to theedge of the heel seat to guide the last in its turning movement duringthe operation of trimming around the edge of the heel portion of theinsole I), this guide member having a lip 12 to project between thebottom of the last and the insole for the purpose of positioning thelast axially of the cutter and supporting the insole out of contact withthe last adjacent to the point of operation of the cutter, as well aspreventing any possible engagement of the cutter with the last, all asmore fully explained in the patent hereinbefore referred to. The guidemember 10 is mounted adjustably in a support 14 which is pivoted to theframe 2 at 16 to permit the member to be swung away from the cutter whenit is desired to remove the cutter from its shaft. Mounted upon theshaft 4 also to rotate therewith is a presser member 18 which is movablelengthwise of the shaft and during the trimming operation is held bymeans of a light spring 20 against the insole adjacent to the point ofcut to assist in preventing the insole from bending away from thecutter. This member is preferably formed .as a spider with its armsextending inwardly between the teeth of the cutter (see Fig. 3) andacross the edge of the insole being trimmed. A collar 22 secured to theshaft by a screw 24 that projects through a slot 26 in a sleeve 28extending from the member 18 serves as an abutment for the spring 20 andby engagement with the inturned end of the sleeve determines the idleposition of the presser member 18 so as to )ermit the insole to forcethe member back s ightly in opposition to the spring 7-20 when theinsole is'present-ed to the cutter.

Secured upon one side of the lower portion of the frame 2 is a bracket30 provided with a horizontal arm 32 upon which the work support of themachine is mounted. This a-r m is provided at its outer end with abearing 33 for the reception of a stem 34 which projects from a block36. The block 36 is thus permitted to turn with reference to the {M11132within limits determined by a stop 38 upon the arm with which the blockis arranged to engage. Projecting from the block 36 at right angles tothe stem 34 is a rod 40 which provides a bearing for the upwardlyextending arm 42 of the work support. Mounted upon the upper end of thearm 42 is a head44 having a stem 46 which engages in a bore in an oifsetpor tion of the arm so that the head may. turn to a limited extent in aplane transverse to the arm. The head 44 has depending therefrom a pin48, Fig. 6, which enters a recess 50 formed in the upper end of the arm42, and threaded through the arm at opposite sides are screws 52 theinner ends of which extend into the recess 50 and serve by engagementwith the pin 48 to limit adjustably the turning movement of the head44in both directions about the axis of the stem 46. The purpose of suchturning movement of the head 44 will be hereinafter explained.

Secured in a bore in the head 44 is a sleeve 54 through which extends aspindle 56 the forward end portion of which is arranged to enter thelast pin socket of a last as shown in Fig. 2.. The spindle 56 is freeboth to move endwise and. to turn within the sleeve. The sleeve54 isextended at one side of the head to provide a bearing for a bracket 58which is mounted thereon for rotation about the axis of the spindle 56,the sleeve having a flange 59 at its outer end to retain the bracket inposition thereon, as shown in dotted lines in Fig. 2. Secured to thespindle 56 at a distance from its forward end is a plate 60 which isformed with grooves62 to provide a slideway for a pair of lastpositioning members64, these members being movable upon the slidewaytoward and from the spindle 56. The members 64 fcomprise a pair of jawsarranged for engagement with the sides of the neck portionof a last toassist in maintaining the last firmly in position upon its support.Pivoted on one side of the plate arebell crank levers 66 in one arm ofeach of which is formed a slot for the reception of a pin 68 whichprojects from the corresponding jaw 64, as shown in Fig. 2. A spring 7 0is connected to the levers 66 in. such manner as to cause the jaws 64 tobe separated as far as permitted by pins 72, the outer ends of which areseen in Fig. 2, these pins projecting at their innerends in position tobe engaged by the jaws 64 in their outward movement, as will. be readilyunderstood. The other arms of thelevers 66 project inwardly in positionto be engaged by the neck of the last when the last the spindle. It willthusbe seen that when a last is mounted upon thespindlc and is moved tocause the spindle to approach the bottomofthejlast pin socket, thelevers 66 will be engaged by thelast and swung about is mounted upontheir pivots, thus causing the aws 64 to slide inwardly and make firmcontact with the sides of the neck portion of the last so as to preventthe last from tipping and assist in maintaining it in fixed relation tothe spindle during the trimming operation.

From a consideration of the construction as thus far described it willbe seen that after a last has been positioned upon the forward endportion of the spindle 56, end

, wise movement of the spindle, which carries the other portionsof thelast support including the plate 60 and the jaws 64, will serve toeffect displacement of the last transversely of the plane of its heelseat portion, and during such movement the last is carried from ortoward the bracket 58 which is restrained from similar movement by thehead 44 and the flanged end 59 of the sleeve 54. Extending from theplate 60 are pins 74 which are arranged for sliding engagement inrecesses in the bracket 58 as the plate is moved toward or from thebracket by endwise movement of the spindle 56, this arrangen'ientserving to maintain the bracket 58 and the last support in the sameangular relation with reference to rotation about the axis of thespindle 56 so that the bracket and the support must rotate in unison.

The means for the last comprises mechanism mounted upon the bracket 58,and including a member 7 6 which is arranged for sliding movement insubstantially parallel relation to the spindle 56. Secured upon theslide 76 by means of a thumb screw 78 is an arm 80 which is formedclamping the insole upon of the heel portion and is bent to extendinwardly over the last bottom to substantially.

the longitudinal median line of the last. This armcarries a clamp member82 which ex tends therefrom toward the rear of the heel seat and has aplurality of pointed pins 84 for efl'ecting secure engagement with theinsole. The member 82 is formed of slightly resilient material and isinclined somewhat with reference tothe plane of the last bottom,as'shown in Fig. 3, so as to permit the clamping device to bemanipulated readily notwithstanding slight variations in the thicknessof difierent insoles or the height of different lasts. By means of ascrew and slot connection 86 the clamp member is adjustable withreference to the arm 80 to vary the position of its insole engagingportion with reference to the rear end of the heel seat, particularlyfor the purpose of accommodating the device to lasts of different stylesand sizes. The arm 80 has a slot 88 in which is received a projection 90of the slide 76 to maintain the armin the same angularrelationto theslide and permit the arm to be adjusted lengthwise ofthe slideto adapt.the device for considerable variations in the height cf diiferent stylesor sizes of lasts.

Pivoted at 92 upon the bracket 58 is a lever 94, the opposite endportions of which are connected by means of links 96 and 98 respectivelywith the slide 7 6 and the plate 60 of the last support. It will bereadily seen that with this arrangement endwise movement of the spindle56 in either direction will cause the slide 7 6 and the clamp member 82to move in the opposite direction. A spring 100 connected at one end tothe slide 76 and at its other end to a portion of the bracket 58, asseen in Fig. 4, tends to maintain the clamping device and the lastsupport in positions in which the clamp member 82 is relatively remotefrom the end of the spindle 56 so as to permit a last to be readilymounted upon the spindle without interference from the clamp member.

The operating means for effecting the clamping of the insole comprises alever 104 pivoted at 102 to the head 44, and connected by links 106 witha bar 108 which is mounted loosely upon the spindle 56 between collars110 on the spindle. Between the bar and the forward collar 110 is a ballbearing 112 which is arranged to facilitate the rotation of-the spindlethrough the turning movement of the last when the lever is held inposition to effect the clamping of the insole. WVith this device theoperator can readily eflect with one hand such relative movement of thelast support and the clamp member as to clamp the heel portion of theinsole securely in position upon the last and position the last firmlyupon its support for the trimming operation. A grip member 114 on thehead 44 assists the operator in operating the lever and in maintainingit in position to clamp the work while the work positioning means,including the last support and the clamping device, are rotated throughthe turning movement of the last which is effected by the other hand ofthe operator.

In order to maintain the work positioning means when idle in a positionconvenient for the reception of a last, the bracket 58 is provided witha weight 116 which tends to occupy the position shown in Figs. 1 and 2,thus presenting the last support in such relation to the operator thathe may conveniently mount a last upon the spindle 56 between the members64 while holding the last by the forepart in the usual manner. In orderto prevent the bracket 58 and the parts which are rotatable therewithfrom swinging unduly upon the removal of a last from the spindle andfurther to insure that the last support shall be maintained in aposition convenient for the reception of a last, the head 44 is providedwith a slot 118 and the pins 7 4 are of such length that their endportions are caused to enter this slot as the last support moves towardthe bracket under the influence of the spring 100. Should the bracketstart to swing when the work is removed, the pins will readily engage inthe slot 118 and lock the bracket against further movement until it hasbeen released by the manipulation of the lever 104. 7

It will be seen that by reason of the arrangement of the rods orspindles34 and 40 the work support is afforded a substantially universalswinging movement to facilitate the presentation of the work to themachine and that the weight of the support will tend to swing it towardthe front and toward one side of the machine about the respective axes40 and 34. In order partially to counterbalance the support and assistin presenting the work to the machine, the arm 42 has an extension 120which projects rearwardly and to the opposite side with reference to therespective axes 40 and .34 and carries a plunger 122 which is arrangedto engage the lower side of the arm 32 and is operated by a spring 124so as partially to counterbalance the work support in its tendency toswing both toward the front and the side of the machine. The tension ofthe spring 124 may be varied by means of a screw 126.

In addition to the substantially universal swinging movement of the worksupport, by reason of the manner in which the arm 42 is mounted upon thesupporting bracket 32, the head 44, as hereinbefore explained, ispermitted to turn relatively to the arm 42 within the limits set by thescrews 52. This arrangement affords provision for such angular variationbetween the axis of turning movement of the last and the axis of thecutter as is desirable in order to permit the insole to be trimmed tothe edge of the lastbottom on lasts of different shapes.

It will be evident from the preceding description thatthe operator maymanipulate the work support to carry the work toward or from positionto'be operated upon by the machine and may also manipulate the lever 104 toeifect the clamping or releasing of the insole by the use of one hand,thus affording him the free use of his other hand to mount the last uponthe support or to remove it therefrom and to turn the last to cause thecutter to trim around the heel seat. With the parts in their idlepositions it is only necessary, in order to position the work, to mounta last upon the end of the spindle 56 and to swing the lever 104 towardthe grip member 114, thus moving the last toward the clamp member 82 andsimultaneously moving this member toward the last bottom to effect theclamping of the insole. As pressure is applied upon the insole by themember 82, the last will be forced farther inward upon the spindle andthe jaws 64,3through the operation of the levers 66, will becaused topress upon the neck of the last at opposite sides to hold it firmly inposition. Movement of the lever simultaneously unlocks the bracket.

58 by withdrawing the ends of the pins 74: from the slot 118, aspreviously explained. The operator then swings the work support to carrythe insole toward the a cutter, this swinging movement being assisted bythe operation of the spring plunger 122. When the parts have beenpositioned in operative. relation to the cutter, as shown in Fig. 3, thelast is turned to cause the cutter to operate around the heel seat uponall portions of the edge of the insole which it is required to trim, thelast support and the clamp member and their connections, together withthe bracket 58, being arranged toturn with the last, and relatively tothe lever 104, in the manner previously explained. Then the support isswung away from the cutter and the lever 10a is released, the spring 100immediately returns the parts to their idle positions, thus releasingthe work and permitting the last to be removed from the spindle.

It will be seen by reference to Fig. 3 that the presser member 18constructed and positioned as shown and described presents noobstruction to the clamping device during the manipulation of the workand by pressure upon the insole adjacent to the point of out assists inpreventing the insole from being deflected by the cutter. It willalso bereadily understood that thearm 80 and other portions of the clampingdevice constructed as shown and described oppose'no obstruction to thecutter in performing the usual trimming operation required in order toconform the heel portion of the insole to the contour of the edges ofthe heel seat of the last.
